Some implementations of the disclosure are directed to symbol-timing tracking systems and methods. A symbol-timing tracking system may include: an ADC to generate a digital signal by sampling an analog signal received at a receiver; an interpolator to adjust a sampling rate of the digital signal; a receive filter to apply a receive filtering function to the digital signal to generate a filtered signal; a timing error detector configured to generate a timing error signal from the filtered signal; a high-order loop filter to filter the timing error signal to generate a filtered timing error signal; and a numerically controlled oscillator to control timing data based on the filtered timing error signal and provide the timing data to the interpolator, wherein the interpolator is to correct for timing of the digital signal and adjust the sampling rate of the digital signal based on the timing data.
